Pedro Sánchez and the Chinese president, Xi Jinping, in their meeting at the end of last year ANDRES MARTINEZ CASARES / Ap-LaPresse fernando h. valls Madrid Pedro Sánchez returns to China, for the fourth consecutive year, on a trip with a markedly economic character that differs this time from the previous three in one aspect. To the recurring objective of rebalancing the trade balance, since imports from the Asian giant are still far superior to exports from Spanish companies –the trade deficit grew to 42 billion last year-, is now added the mission of trying to open business to high value-added companies. Spanish investment in China is currently concentrated in areas such as automotive, financial services, or machinery. Companies like Santander, BBVA, or Inditex have a presence in the country, where more industrial-profile groups, such as the engineering group Técnicas Reunidas or the automotive suppliers Antolin, CIE, and... also operate.
